A data leak on an adult platform can be especially sensitive because it may expose not only login and payment information, but also membership records, identity-verification documents, or activity associated with the account.

You do not need to wait for the platform to publicly confirm a breach before taking reversible protective steps. First determine what type of information may have been exposed, because a leaked password, card number, identity document, and viewing history require different responses.

Information that may be exposed	First action	When to escalate
Email address and password	Secure the email account, change reused passwords, and enable two-factor authentication	Another account uses the same password or an unknown login appears
Card or payment information	Lock the card and contact the issuer through its official channel	An unfamiliar charge or payment authorization appears
Resident registration number or identity-document image	Register the exposure with Korea’s financial identity-protection system	The data could be used to open accounts, obtain loans, or issue cards
Membership or activity history	Preserve evidence and prepare for targeted phishing or blackmail	Someone threatens disclosure or demands money

Secure the Email Account Before the Platform Account

Before deleting the account, preserve the platform’s breach notice, unfamiliar login records, password-reset emails, account changes, and suspicious transactions. These records may be needed for a payment dispute or police report.

Open the service by typing its official address or using its official app. Do not sign in through a link contained in a breach-warning email or text message.

Change the password of the connected email account first. An attacker who controls the inbox may be able to reset the platform password again. After securing the email, change the platform password, sign out of other sessions, review the recovery email and phone number, and enable two-factor authentication where available.

If the same or a similar password was used elsewhere, replace it first on services that could cause the greatest harm: email, banking, payment services, cloud storage, social media, and mobile carrier accounts.

Korea’s official Find My Leaked Information service can check whether an email address or login credential appears in known illicitly distributed data. The service is operated by the Personal Information Protection Commission and KISA; its email-search function was expanded in January 2026. Use the official service rather than an unknown breach-checking site that asks for your current password.

Protect Payments and Identity According to What Was Exposed

If card details may have been stored by the platform, lock the card through the issuer’s official app or emergency number. Ask whether the card should be replaced and whether the merchant’s recurring payment authorization needs to be blocked separately.

Review both completed and pending transactions. Pay attention to unfamiliar merchant names, foreign-currency charges, repeated subscription attempts, and small test payments that you did not authorize.

Report an unauthorized card payment directly to the card issuer. When money has already been transferred as part of a scam, contact the relevant financial institution and call 112 immediately to request payment suspension and further assistance. Korean financial authorities advise victims of financial phishing losses to contact the financial company or the integrated reporting channel without delay.

A stronger response is appropriate when the exposed data includes a Korean resident registration number, an identity-card image, bank authentication information, or a selfie used for identity verification.

In that case, use the Financial Supervisory Service’s Personal Information Exposure Accident Prevention System. Once registered, the exposure information is shared with financial companies so that enhanced identity checks can be applied when someone attempts a transaction in your name. Registration may also restrict legitimate activities such as opening a new account or applying for a card, so it is most appropriate when sensitive identity data – not merely an email address – has been exposed.

People facing a substantial identity-theft risk can also consider Korea’s loan and non-face-to-face account-opening safety-blocking services through a participating financial institution’s branch or mobile app. These measures are designed to help prevent unauthorized loans and new accounts.

Treat Messages About the Platform as a Possible Second Attack

After a leak, a scammer may send a message that mentions the adult platform, quotes an old password, claims to possess your activity history, or threatens to contact your family or employer.

A real password in the message may indicate that credential data was obtained. It does not, by itself, prove that the sender controls your camera, contacts, cloud storage, or private files.

Do not reply, negotiate, send money, open an attachment, or install an application supplied by the sender. If a message claims that you must “verify” the account, open the platform directly through its official address instead of following the link.

Preserve the full message and record the sender’s address, phone number, payment account or cryptocurrency wallet, timestamps, and exact demand. Screenshots are useful, but the original email or message should also be retained where possible.

If someone demands money or threatens to disclose personal information, contact 112 for an urgent situation. Korea’s Electronic Cybercrime Report System can also be used to prepare a cybercrime report and supporting statement online; formal criminal-case handling may still require a police-station visit.

Korea’s official phishing-response service also identifies video-distribution threats and related extortion as scam scenarios that should be reported rather than handled privately with the sender.

Ask the Platform What Was Actually Exposed

Contact the platform through its official support channel and request specific information rather than a general apology.

Ask which data categories were affected, when the unauthorized access began and ended, whether passwords were securely hashed, whether the platform or a separate payment processor stored card information, whether identity-verification documents were involved, and whether all active login sessions have been invalidated.

Also ask the platform to provide a dated copy of its response and explain how you can delete stored identity and payment information. Do not close the account until you have preserved relevant evidence and removed or replaced connected payment methods.

For advice about a personal-information infringement in Korea, contact KISA through 118. The Korean Personal Information Portal also provides routes for infringement reports and dispute mediation when a data handler does not respond appropriately.

After the immediate response, monitor only the services connected to the exposed data. A leaked password requires attention to accounts where that password was reused. Exposed card information requires transaction monitoring. Exposed identity documents justify monitoring for unauthorized financial activity.

Do not activate every available financial restriction simply because the platform sent a vague security notice. The response should match the actual exposure.

The correct response depends on the type of information exposed. Use the table below to identify the first action to take and when the situation requires formal reporting.

Final Action Rule

The correct response depends on the type of information exposed. Use the table below to identify the first action to take and when the situation requires formal reporting.

Situation	Immediate action	Next step
Only account credentials may be exposed	Secure the connected email account first, change the platform password, replace reused passwords, and enable two-factor authentication.	Review active sessions, recovery details, and other accounts that used the same or a similar password.
Payment information may be exposed	Lock the card or payment method and contact the issuer through its official channel immediately.	Ask whether card replacement, recurring-payment blocking, or a transaction dispute is necessary. Do not wait for an unauthorized charge to appear.
Official identity data may be exposed	Use Korea’s financial identity-protection and transaction-blocking systems.	Consider blocking unauthorized loans or non-face-to-face account openings, especially if an ID image, resident registration number, or banking-verification data was exposed.
Someone threatens disclosure or demands money	Preserve the full message, sender details, payment instructions, timestamps, and other evidence.	Report the incident to the police or the appropriate cybercrime channel. Do not pay, negotiate, open attachments, or follow links supplied by the sender.
